How Big

[debo78]

]I went ti the pet store, and the guy gave me a deel on red belly piranhas, and I had to take the whole tank of six. They're currently an inch in a half to 2 inches long. How big of a tank do I need to keep all six alive and healthy?

their adult siz is 18" plus you will need an extra huge tank to keep them all healthy and alive.

They like to have a huge tank to swim around in, so I'm guessing a tank 200 gallons or so, the bigger the better.

since they like to school 6 is a good amount but you would need to have a huge tank to have them.

imo,dont get them!

They get huge as has been already stated. Also there boring,as they get older they will just sit around the tank waiting to be feed.

While I think they are kind of cool and pretty in thugish kind of way there just not worth it in the long run!
